30p from GH2?
The GH2 only has 60i or 24p video output. Has anyone heard about either an upgrade or firmware hack that will allow 30p output?

Or 60p which the sensor does record, that would be nice. Also iso limit in movie mode.

ISO limit in video mode is 3200. It does a pretty good job of it too.
I believe it does 30p in MJPEG. |

If you shoot in 1080 24p mode at the 80% speed settings.....supposedly that is 30p...but with no sound.

Thanks Mike. I will have to try that when I get my GH2. No audio is a bit of a downer but not much since I usually record alternate audio anyway.

Is 24p actually 23.976? The reason I ask is that if it is, 80% of 29.97 is 23.976. If it is, then it will be at the same frame rate as 29.97 video. If not, the frame rate won't exactly match so it will take a couple of extra steps to deal with that when editing. It's a bit like the old 5D Mk. II problem of recording at 30p instead of 29.97.

It has an MJPEG mode that records to 720 30p.

I was thinking more like limiting it to iso 800. From what I can see there is no way to set alimit in video mode. |

Why not shoot in manual? This way you can lock the ISO. That's what I do in a lot of my low light shooting.

Paulo, I am shooting the gh2 as a wide-angle lock off in 'set-it-and-forget-it' mode. Shooting a theatrical production, with widely varying lighting and with the stock 14-42 mm lens.
Actually, manual mode doesn't quite work... In the end, I set it to Shutter priority, shutter at 60, manual iso at 800 and let the 'exposure compensation' give me everything it's got. There is one dark scene I need to quickly reset to iso 1600 and even then it's dark,; I have the two camera settings as Custom 1 & 2 so I don't have to fumble with the menu in the dark. The gh2 is giving me a very contrasty picture and trying to CC it in Premiere Pro I hit noise real fast. My shoot is attacking this camera/lens combo at so many of its weaknesses, low light, noise floor, contrasty dynamics, no 'Spot' function per se, shooting at 60i to match my FX-1 instead of 24p, etc. etc. After this shoot I look forward to working with more even lighting in the iso 400 range on some nice corporate interview gig :-) |
